What is GHRP-2?

GHRP-2 is a growth hormone axis peptide studied for gh release in adult gh deficiency and appetite stimulation in cachexia models. Below is an educational overview of GHRP-2 peptide benefits, mechanism, common research protocols, dosage references, and known side effects.

GHRP-2 Mechanism of Action

A synthetic hexapeptide that activates the ghrelin/GHS-R1a receptor, stimulating endogenous GH release. Compared to Ipamorelin, GHRP-2 produces a stronger GH pulse but also modestly elevates cortisol, prolactin, and appetite.

GHRP-2 Research Areas & Benefits

GH release in adult GH deficiency
Appetite stimulation in cachexia models
Diagnostic GH stimulation testing

GHRP-2 Dosage & Common Research Protocols

Stacked with GHRH analog

Combined with CJC-1295 or Sermorelin in research to amplify GH pulse amplitude.
